Use Postman from your AI

Work with Postman workspaces, collections, requests, environments, specs and mocks, and run collections through Postman's official MCP server (minimal tool set). Connect by signing in.

Enable Postman in ArletPostman official docs

Arlet makes Postman's official MCP server available from the AI client you already use. Signing in completes the connection.

The AI can work with workspaces and collections, add and update requests, manage environments, specs and mocks, and run collections. This uses the US region's Minimal configuration (about 40 core tools); the available tools are those provided by Postman's official server.
